When the inflation is very moderate, it acts as an incentive to traders and producers. The profit due to rising prices encourages and induces business class to increase their investments in production, leading to generation of employment and income.
(i) However, hyper-inflation results in a serious depreciation of the value of money and it discourages savings.
(ii) When the value of money undergoes considerable depreciation, this may even drain out the foreign capital.
(iii) With reduced capital accumulation, the investment will suffer a serious set-back which may have an adverse effect on the volume of production.

Duesenberry has made two observations regarding the factors affecting consumption.
a) The consumption expenditure depends not only on his current income but also past income and standard of living. As the individuals are accustomed to a particular standard of living, they continue to spend the same amount on consumption even though the current income is reduced.
b) Consumption is influenced by demonstration effect. The consumption standards of low income groups are influenced by the consumption standards of high income groups. In other words, the poor people want to imitate the consumption pattern of rich. This results in spending beyond their income level.

i) Use of restrictive measures for BoP problems has declined markedly.
ii) Services trade has been brought in to the multilateral system and many countries.

The followings are some of the National Income Identities:
NNP = GNP - Depreciation
NNI = NNP - Indirect taxes
PI = NNI - Retained earnings, corporate taxes and interest on public debt
PDI = PI - Personal taxes
Where,
GNP = Gross National Product
NNP = Net National Product
NNI = Net National Income
PI = Personal Income
PDI = Personal Disposable Income

(i) Besides verification it is used for the prediction of one value, in relation to the other given value.
(ii) Regression coefficient is an absolute figure. If we know the value of the independent variable, we can find the value of the dependent variable.
(iii) It has wider application, as it studies linear and nonlinear relationship between the variables.
(iv) It is widely used for further mathematical treatment.

(i) Electronic waste is the new by product of the Info Tech society.
(ii) It includes a growing range of electronic devices from household appliances, such as refrigerators, air conditioners, cell phones, computers.
(iii) e-waste can be defined as the result when consumer, business and household devices are sent for re-cycling (e.g., television, computers, audio-equipments, VCR, DVD, telephone, Fax, Xerox machines, wireless devices, video games).

Let sales of a firm be denoted by X and expenses be denoted by Y
Calculations for Coefficient of Correlation

\(\bar { X } =\frac { \sum { X } }{ N } =\frac { 580 }{ 10 } =58\ and\ \bar { Y } =\frac { \sum { Y } }{ N } =\frac { 140 }{ 10 } =14\)
Applying the Eq. (4.3a), we have, Pearsonian coefficient of correlation
\({ r }_{ xy }=\frac { { \sum { d } }_{ x }{ d }_{ y } }{ \sqrt { { \sum { d } }_{ x }{ ^{ 2 } }d_{ y }^{ 2 } } } \)
\({ r }_{ xy }=\frac { 70 }{ \sqrt { 360x22 } } \)
\({ r }_{ xy }=\frac { 70 }{ \sqrt { 7920 } } \)
\({ r }_{ xy }=0.78\)
The value of = 0.78 xyr , indicate a high degree of positive correlation between sales and expenses.

Types of Exchange Rate:
(i) Nominal Exchange Rate
(ii) Real Exchange Rate
(iii) Nominal Effective Exchange Rate
(iv) Real Effective Exchange Rate If 1US Dollar = Rs.75 
(i) Nominal Exchange Rate:
Nominal Exchange Rate =\(\cfrac { 75 }{ 1 } \)
This is the bilateral nominal exchange rate.
(ii) Real Exchange Rate:
(1) Real Exchange Rate = \(\cfrac { { eP }_{ r } }{ P } \)
P = Price level in India
PF = Price level in abroad (say US)
e = Nominal Exchange Rate 
(2) If a pen costs Rs.50 in India and it costs 5 USD in the US.
\(\therefore \text {Real Exchange Rate}=\cfrac { 75\times 5 }{ 50 } =7.5\)
(3) If real exchange rate is equal to 1, the currencies are at purchasing power parity.
(4) If the price of the pen in US is 0:66 USD, then the real exchange rate

Then it could be said that the USD and Indian rupee are at purchasing power parity.

1. Human Resources
(i) Human resource is named as human capital because of its power to increase productivity and thereby national income. There is a circular relationship between human development and economic growth.
(ii) If labour is efficient and skilled, its capacity to contribute to growth will be high. For example Japan and China.
2. Technical Know-how: As the scientific and technological knowledge advances, more and more sophisticated techniques steadily raise the productivity levels in all sectors.
3. Political freedom: The process of development is linked with the political freedom.
4. Social organization: People show interest in the development activity only when they feel that the fruits of development will be fairly distributed. Mass participation in development programs is a pre-condition for accelerating the development process.
5. Corruption free administration:
Corruption is a negative factor in the growth process. Unless the countries rootout corruption in their administrative system, the crony capitalists and traders will continue to exploit national resources. The tax evasion tends to breed corruption and hamper economic progress.
6. Desire for development:
The pace of economic growth in any country depends to a great extent on people's desire for development.
7. Moral, ethics and social values:
(i) These determine the efficiency of the market.
(ii) If people are not honest, market cannot function.
8. Casino Capitalism:
If People spend larger proportion of their income and time on entertainment liquor and other illegal activities, productive activities may suffer.
9. Patrimonial Capitalism:
If the assets are simply passed on to children from their parents, the children would not work hard, because the children do not know the value of the assets. Hence productivity will be low.

(i) Strong economic growth or high GDP growth leads to excessive use of resources.
(ii) Natural resources are essential inputs for production in many sectors;
(iii) Production and consumption lead to pollution and other pressures on the environments.
(iv) Poor environmental quality affects economic growth and well being by lowering the quantity and quality of resources or due to health impact.
(v) There is the need to balance growth and the sustainability of eco system.
(vi) So we have to ensure our sustainable existence, consume less and curb economic growth.

Principle of Independence
(i) A Government should be autonomous and free about the internal financial matters concerned.
(ii) Each Government should have separate sources of revenue, authority to levy taxes, to borrow money and to meet the expenditure.
Principle of Equity
(i) The resources should be distributed among the different states so that each state receives a fair share of revenue.
Principle of Uniformity

(ii) The Bank supplements private investment by providing finance for productive purpose out of its own resources or from borrowed funds.
Technical services
(i) The World Bank facilitates different kinds of technical services to the member countries through Staff College and experts.

Cyclical Disequilibrium
Cyclical Disequilibrium occurs because of:
(i) Two countries may be passing through different phases of business cycle.
(ii) The elasticities of demand may differ between countries.
Secular Disequilibrium
(i) It occurs because of long-run and deep rooted changes in an economy as it advances from one stage of growth to another.
(ii) In the initial stages of development, domestic investment exceeded domestic savings and imports exceeded exports, as it happened in India since $1951.
Structural disequilibrium
(i) Structural changes in line economy may also cause BoP disequibrium
(ii) Structural changes include development of alternative sources of supply, development of better substitutes, exhaustion of protective resources or changes in transport routes and costs.

Introduction
The functions of commercial banks are broadly classified into primary, and secondary functions
1) Primary Functions:
Accepting Deposits
Demand Deposits
1. It refers to deposits that can be withdrawn by individuals without any prior notice to the bank.
2. Depositors can withdraw money at any time by writing a withdrawal slip or a cheque or from ATM centres
Time Deposits

2. It has higher interest.
3. Deposits can be withdrawn only after a specific time period
Advancing Loans
1. Banks grant loans to individuals and businesses in the form of overdraft, cash credit and discounting bills of exchange.
2) Secondary Functions
Agency Functions
1. Commercial banks act as agents of customers by performing various functións.
Collecting Cheques
1. Banks collect cheques and bills of exchange on behalf of their customers through clearing house facilities provided by the central bank.
Collecting Income
1. Banks collect dividends, pension, salaries, rents and interests on investment on behalf of their customers.
2. A credit voucher is sent to customers for information when any income is collected by the bank.
Paying Expenses
1. Telephone bills, insurance premium, school fees and rents can be paid through banks.
2. A debit voucher is sent to customers for information when expenses are paid by the bank.
3) General Utility Functions
Providing Locker Facilities
1. Locker is provided for safe custody of jewellery, shares, debentures and other valuable items.
2. This minimizes the risk of loss due to theft at home.
Issuing Traveller's Cheques
1. Banks issue traveller's cheques to individuals for travelling outside the country.
2. These cheques are safe and easy way to protect money.
Dealing in Foreign Exchange
1. Banks provide foreign exchange to businessmen dealing in exports and imports.
2. But they need to take the permission of the Central Bank for dealing in foreign exchange.
4) Transferring Funds

Electronic Banking
1. It includes services, such as debit cards, credit cards and Internet banking.
6) Other Functions
Money Supply
E.g: A bank lends Rs.5 lakh to an individual and opens a demand deposit in the name of that individual.
1. Bank makes a credit entry of 25 lakh in that account.
2. This leads to creation of demand deposits in that account.
3. Thus, without printing additional money, the supply of money is increased.
Credit Creation
1. It means the multiplication of loans and advances
2. Banks receive deposits from the public and use these deposits to give loans.
3. However, loans offered are many times more than the deposits received by banks.
Collection of Statistics
1. Banks collect and publish statistics relating to trade, commerce and industry and advice customers and public authorities on financial matters.

Introduction
The concept of multiplier Was first developed by R.F. Khan in terms of employment. J.M Keynes redefined it as investment multiplier.
Definition
Multiplier is defined as the ratio of the change in national income to change in investment.
\(K=\Delta Y / \Delta I\)
The value of multiplier depends on MPC.
\(\mathrm{K}=\frac{1}{1-\mathrm{MPC}} \text { since } \mathrm{MPC}+\mathrm{MPS}=1\)
\(k=\frac{1}{N 118}\)
Multiplier is inversely related to MPS and directly with MPC.
If MPC is, 0.75, MPS is 0.25 then K=4.00
\(\frac{1}{1-0.75} \text { or } \frac{1}{0.25}=4\)

Working
(i) Suppose government undertakes investment expenditure equal to र100 cr on public works.
(ii) Income of labourers and suppliers of materials increases by र100 cr
(iii) If MPC is 0.8 that is 80 %. र80 cr is spent on consumption र20 cr salved
(iv) Suppliers of goods get an income of र80 cr. They spend र64 cr (ie 80% of र80 cr).
(v) In this manner consumption expenditure and increase in income act in a chain like manner.

Cyclical unemployment:
(i) During the downturn phase (recession and depression) of trade cycle, income and output fall leading to cyclical unemployment.
(ii) It is caused by deficiency of effective demand
Structural unemployment:
(i) Unemployment due to massive and deep rooted changes in economic structure leads to structural unemployment.
(ii) Lack of demand for the product or shift in demand to other products cause this type of unemployment.
(iii) (e.g.) rise in demand for mobile phones has adversely affected the demand for cameras, tape recorders
Disguised unemployment:
(i) It occurs in agriculture when more people are there than required. Even if some workers are withdrawn, production does not suffer.
Actual marginal productivity is zero, less or negative.
(i) Seasonal unemployment
1. In agriculture and agro based industries like sugar, production activities are carried out only in some seasons.
2. These industries offer employment only during that season in a year.
3. People remain unemployed during the off season.
4. Seasonal unemployment takes place from demand side also (eg) ice cream industry, holiday resorts
(ii) Frictional unemployment (Temporary unemployment)
1. It arises due to imbalance between supply of labour and demand for labour.
2. It is because of immobility of labour, lack of necessary skills, break down of machinery, shortage of raw materials.
3. The persons who lose jobs and in search of jobs also come under frictional unemployment
(iii) Educated unemployment
1. Educated people are underemployed or unemployed when qualification does not match the job.
2. Faulty education system, lack of employable skills, mass student turnout and preference for white collar jobs are highly responsible for educated unemployment.

Introduction:
National income can be measured by the social accounting method. Under this method, the transactions among various sectors such as firms, households, government are recorded and their interrelationships traced.
Firms:
undertake productive activities. They employ factors of production to produce goods and services.
Households:
Households are consuming entities. They represent the factors of production, who receive payment for services rendered by them to firms. (i) Households consume the goods produced by the firms. There is a circular flow of money between these two groups.
Government:
The Government sector refers to the economic transactions of public bodies at all levels-centre, state and local. Their purchases may be financed through taxation, public borrowings. The government provides public health, education. They satisfy the collective wants of society. But Post Offices and railways are separated from the Government sector and included as "Firms".
Rest of the world:
It relates to international economic transactions - income, export, import external loan transaction, and allied overseas investment income and payments.
Capital sector:
(i) Capital sector refers to saving and investment activities. It includes the transactions of banks, insurance corporations, financial houses. These are not included under "Firms".
(ii) The economy is also divided into primary, secondary tertiary and quaternary sectors.
Conclusion:
The social accounting framework is useful for economists as well as policy makers, because it represents the major economic flows and statistical relationships among various sectors of the economic system. It is possible to forecast the trends of economy more accurately.

(i) It refers to deposits that can be withdrawn by individuals without any prior notice to the bank.
(ii) In other words, the owners of these deposits are allowed to withdraw money anytime by writing a withdrawal slip or a cheque at the bank counter or from ATM centres using debit card.

“The accelerator coefficient is the ratio between induced investment and an initial change in consumption."

1. Macroeconomics in its modern form, began with John Maynard Keynes and his book “The General Theory of Employment, Interest and Money” published in 1936.
2. Keynes offered an explanation for fallout from the Great Depression, when goods remained unsold and workers unemployed.
3. Hence, Keynes is regarded as the ‘Father of Modern Macro Economics’.

(i) Ceteris paribus (constant extraneous variables).
(ii) Existence of Normal Conditions.
(iii) Existence of a Laissez-faire Capitalist Economy.

Environmental goods are typically non-market goods, including clear air, clean water, landscape, green transport infrastructure, public parks, rivers, mountains, forest and beaches.

1. Loans out of its own fund.
2. Loans out of borrowed capital and
3. Loans through Bank's guarantee.

(i) Plastic money refers to the hard plastic cards used everyday in place of actual bank notes.
(ii) They aim at removing the need for carrying cash to make transactions.
(iii) (E.g.) Cash cards, Credit cards, Debit cards, Pre-paid Cash cards, Store cards, Forex cards and Smart cards.

(i) It arises due to imbalance between supply of labour and demand for labour.
(ii) It is because of immobility of labour, lack of necessary skills, breakdown of machinery, shortage of raw materials.
(iii) The persons who lose jobs and in search of jobs are also included.

(i) NDP = GDP - Depreciation.
(ii) NNP = GNP - Depreciation.
(iii) The difference between NDP and NNP is the net factor income from abroad.
(iv) In NDP it is excluded but in NNP it is included.
